'.To all whom it may concern.-

Be it known that I, CiriiiLns E. SAVAGE, a A citizen of the United States of America, and a resident of Groveton, in the county of Coos and State of New Ham shire, have invented certain new and useful Improvements in Sulfur-Burners, of which the following is a specification. V

Some kindsol sulfur-such, for instance,

as that which is mined in Louisiana and is known to the trade as Louisiana suli'urcontains an oily substance which comes out of the sulfur when it is melted, and this oil being lighter than the sulfur rises to the top This oil at the top'ol' the sulfur prevents perfect combustion and is very objectionable for that reason.

To provide a device in which such sulfur may be readily burned is the object of the present invention; and it consists, primarily,

n a burner which is tilted or rocked over a fixed point, -this tilting preterably being done automatically by means of a hydraulic mechi hi'th' l'l' ll anisni. .1 re era 3 is iytiau it met nm isni is provided with means whereby the burner will be stopped at the end of its movement in either direct-ion and retained in this position for a time before it is moved in the iosite direction. he invention consists, further, in a suitable seal between the movable or rocking oven-casing and the fixed outlet-pipe thereto.

It consists, further, in providing a Inralit-y of oven-casings, the first of wider is 5 controlled by a hydraulic device, while each succeeding oven-casing is controlled by'the movement of the preceding oven-casing.

The invention consists, furthermore, in certain novel features of construction and arrangement of parts, which will be readily 0f the drawings, Figure i represents an elevation of a. burner embodying the lcatures of this invention shown in its lowest position,.while its highest position is indicated in dotted lines. Fig. 2 represents a front eleate in conjunction, certain of the parts being shown in section.

represent sections through the valve by which Water is admitted or exthree -way hausted from the hydraulic cylinders.

Similar characters designate hke arts throughout the'scveral figures of the 'rawin s.

in the drawings, 10 is the oven-casing of a burner of any well-known construction provided near its front end'with a support 11,-to' the upper end of which is pivoted at 12 a wheel 13, over which asses a rope, chain, belt, or other similar t evice 14s to the rear end of which is secured a weightlfi, While its opposite end is'secured to a bail 16, connected to a sliding door 17. The weight 15 practically balances the weight of the door 17, which is slidably mounted in the groove 18 in the casting 19, bolted to the flangeZO at the front end of the oven-casing 10.

The door l'lprovides a ready means for charging, the burner. t some convenient point in the length of the burner is a transverse member 21, extending across the bottomof the oven-casing 10, said transverse member resting in a suitable groove in a rocker-plate 22, of a suitable pier-23. The oven-casing 10 is adapted to rock on this plate 22 by means of the mechanism to be hereinafter described. This rocking or tilting motion or the ovencasing causes first the front end thereof to assume a position below the horizontal plane and then by a reversal of the movement the front end is raised above the horizontal plane and the rear end of the oven-casing is lowered beneath said plane. This tilting movement causes the oily substance which is contained in the sulfur and which separates therefrom during combustion to flow to the lowest point of the oven-casing and leave the sulfur in the upper end free therefrom, so that the sulfur may be burned readily and the gas freed therefrom. These gases pass to the rear end of the oven and escape through the outlet-pipe 24. This pipe is necessarily a hired pipe, and it is obvious that to prevent the gas from escaping at the joint between the pipe and the movable rear end of the vation of 'a pair of burners adapted to operl View of the hydraulic devices for tiltinp the l E provided. Fig. 3 represents a plan oven-casing 10 a hermetical seal must be to the rear end of the oven-casing 10 a casting 25. surrounding the outlet-passage 26 of said oven-easing. This casting 25 is rovided with an annular groove 27, whic IS showing'the seal between said oven-casing supplied with water from the pipe 28. To and the fixed outlet-pipe; and F igs. 5 and 6 l the lower end ofthe outlet-pipe 24 is securedlhis is accomplished by securing mounted upon the upper end i an annular flanged-member 29, the flange of which extends into the water contained in the annular groove 27. It is obvious that by such a'construction the oven-casing is free to rock in either direction without interfering with the fixed outlet-pipe 24, and a hermetical seal is provided, thereby preventing the gas which passes through the outlet 26 from escaping and obliging it to pass into the pipe 24.

While the transverse plate 21 is shown in thedrawings as slightly back of the center of the oven-casing, so that the bulk of the weight of the casing is in front of the pier 23, it is obvious that the nor could be built further to the rear or the pier could be built well to the front of the oven and the automatic rockin device located at the rear of the oven without altering the. principles of this invention. It is also obvious that the same results could be obtained if the ovencasing were rocked transversely rather than longitudinally, the main object of the in-ven tion beingto free, by the tilting or rocking of the oven-casing, a portion of the sulfur contained therein from the oily substance re moved therefrom in the process of combustion and alternately uncover a portion of'the sulfur contained within the oven-casin pin order to produce a complete combustioii of all of the sulfur therein contained.

The pipe 28 connects with. the main supplypipe- 30 and is provided with a valve 31, by which the amount of water flowing throu h said pipe into the annular groove 27 may e regulated. The free end of the burner-cad ing 10 rests upon a round roll, which rests on a piston-rod 32, mounted in a bearing 33 in the cylinder-head .34, while the piston 35 thereof is mounted to be freely revol ubl'e in thecylinder 36'. The cylinder 36 is mounted upon a suitable support 37 ,and' normally the weight of the free end of the burner-cas1ng said stein. bein supported by means of the retains the piston 35 in its extreme lowest position.

A pipe 38 communicates with the interior ofthe cylinder 36 below the lower face of the piston 35 when in its lower position, this pipe communicating with the main upplypipe 30-, and-is provided with a hand Val'Ve 39. The pipe 38 is also provided with a threeway valve 40', having an outlet connected to an exhaust-pi e41. The plug 42 of said valve is provi' ed with a for ed arm 43, the forks of which straddle the stem 44 of a pisten 45, mounted in a smaller cylinder 46,

spider 4 7 and 'aving u on its upper end a weight 4 8-,whichnormal y reta'i s the piston 45 in its lowest position.

The stem 441s provided with collars 49 50, wliichjin the longitudinal movement of said stem 44 contact with the-arm 43' and o era/te the valve 41) to" either admit water-through the pipe 38- into the cylinder 36" or permit, it

remain at a standstill" at each end tilting movement in either 'direction This 'isan important feature ofthc inventiom as to exhaust therefrom through the outlet-pipe 41, as the case may be. A pi. e 51 is provided with a hand-valve 52 an a three-way valve 53. The valve 53 is connected to an exhaust-pipe 54, and the plug of said valve is provided. with a forked arm 55, which'st-raddls a stem 56, secured to a' laterallyextend ing plate 57, fastened to the burner-casing 10. The stem 56.is provided with suitable collars 5'8 58*, which act upon the arm '55 of the valve 53 toadmit water to the cylinder 46 or exhaust it therefrom, as the case may be.

The pipe 51, connecting with the ipe 38 when thd connects with the cylinder 36. valve 39 is opened, permitting a flow of water from the main pipe 30 into the pipe38,'it is prevented from passing into the cylinder 36 by means of the valve 40, which' is normally closed for admission; but it will pass through the pipe 51 of the secondary cylinder 46 and cause the piston 45 therein to be raised to its upper position. In doing this the collar 50 after it is moved u wardly for a short distance will contact wit 1' the forked arm 43 and move this to operate the valve 40 to shut off the exhaust 41 and open said valve to permit the flow of water in the-pipe 38 to pass into the cylinder 36 to raise the front end of the oven-casing into the position shown in dotted lines. The piston 35 is moved upwardly untilit reaches the cylinder-head, where its upward movement is stopped. It remains in this position until the pressure of the liquid beneath it is relieved by the opening of the exhaust.

roo

As the front end of the burner moves -up 'wardly the collar 58 on the stem 56; carried by said oven-casing, will come into contact with the arm 55130 operate the valve 53 to shut off further adinissionthrough the pipe 51 and 0 on to the exhaust 54, thereby permitting. t e weight 48 to act upon the-piston 45 to-retu-rn it to its lower'position, as shown in Fig. 2.

As the piston 45 descends the collar 49 will; move for a slight distance and then come into contact with the forked arm 43 and operate the valve 4Uto;again shut off the v admission to the cylinder 36*andopen-up the exhaust 41, thereby permitting thefront-end 'ot the oven-casing b its weight to mo ve the piston 35 downwar y to its normal position.-

This downward movement of: the front end oi the oven casingwil'l' cause thecol'larj58 to move-downwardly a slight distance-andthen come into" contact with the arm'55- to again *0 enthe valve 53* to admit pressure beneath t 0 piston 45 to repeat the operation lost motion between the'collars 58and 58 in operating upon the arm 55- and thelost-mo- 7 tron between the collars 49 50 in operating This upon the arm 43 cause the oven-casing 0- its senses in b this means the sulfur contained within t e oven has all of the oily substance removed from its upper surface for a suflicient period of time to gel-nut the process of com-' ustion to procee without the interference thereof.

Where two or more burners are used in conjunction, the main Ipipe 30 is continued beneath the additions I vided with branch pipes 60, in each of which is a handwalve 51, by which any articular burner may be shut off when not esired for use; Each pipe 60 connects with the cylinder beneath its respective oven-casing, and each of these pipes 60 is provided with a. three-way valve 62, having an armfiB to cg crate it.- This arm 63 is forked and stra dies a stem 64, dependin from a plate 65, secured to the under side 0 the firstsnentioned oven-casing 10. The stem 64 is provided with collars 66 67, which in the movement of the front end of the casing 10 contact with the arm 63 to open and close the valve 62'to permit each succeeding oven-casin to be, tilted by the admission and exhaust from its hydraulic cylinder, this admission and exhaust being regulated by means of the movement of the preceding oven-casing.

It is believed that the operation of the invention will be thoroughly understood from the foregoing without any further descrip-- tion.
